WHY AM I SO THIRSTY?
By Valerie Lunden, MA
If
you haven't seen the movie Batman Returns then you're missing
out on a super flick. In this latest rendition, Gotham City
(and Batman), are battling the evil water-zapper, a high
tech machine that evaporates water. As you might imagine
this becomes a significant problem for our caped crusader,
who realizes early in the plot that water makes up more
than two-thirds of the weight of the human body, and that
the fate of the human race now rests in his bat gloves.
Batman’s problems could mirror our own, water is
elemental to life. Even explorers who get lost in deserts
rely more on water supplies then food rations for survival.
But if consuming water is so critical to humanity then why
don't we take it more seriously?
For those die-hard folks who can't abide the taste, flavor
and texture of water, well this is not too difficult an
argument. Drinking water is purported to have no taste,
flavor or texture. Maybe this is the point. Flavorless and
tasteless - why even bother drinking the stuff?
As significant as the menu during any dining experience,
water could be considered a relevant part of any meal. Much
like a punctual dinner guest (we hate those, don’t
we?), water is often the first to arrive at the table and
the last to leave. Let's not forget that water is also one
of the only FREE items in the restaurant (not counting the
ketchup, steak sauce, and sugar packets).
Whether the water arrives plain, iced, or with lemon, there
seems to be an unspoken message being passed along regarding
the relevance and necessity of water in our diet. But again,
why do other beverages rank higher? Is it more fashionable
to order something else when water is without a doubt the
best choice?
Well, whatever the reasons for water-disdain, even our
forefathers never knew drinking H20 was key to longevity
and on-going health. They didn’t even know that the
standard drinking requirement is 8 (8 oz) glasses of water
a day (as most nutritionists and commercial diets recommend).
According to the Environmental Protection Agency, water
serves as a lubricant and is the basis of saliva and the
fluids surrounding the joints. Water also regulates body
temperature through perspiration. It even helps prevent
constipation by moving food through the intestinal tract.
In short, we must have water for proper circulation and
to avoid chronic ill health. Are you convinced to drink
more? Not yet!
Here's something else to consider. If surveyed, how many
of us drink eight glasses a day? And those of us who drink
other more fashionable beverages: do those count as far
as the daily requirement is concerned?
Perhaps a thought to keep in mind here is that the body
recognizes consumed beverages (other than water), as foods
that need digesting. Beverages like coffee, (lattes, espressos,
etc.), tea (hot and cold), soda and wine often have more
then one ingredient, so the body identifies them as digestible
foods. In contrast, water seems to be the exception. When
water is consumed, because there are virtually no ingredients
and very little processing, it immediately enters the bloodstream
and is circulated then eliminated.
For argument's sake, let's take a moment to examine just
where water isn't needed. It would appear that there aren't
too many places. The skeleton (all bone), takes up the remaining
body mass. However, in the final analysis, even this might
not be accurate. Even though the skeleton might not directly
need water, it does rely on muscles and ligaments –
which do. On this subject (bones), let's not forget osteoporosis
and all those calcium supplements it is suggested we add
to our diet. Water is required to dissolve calcium and then
transport it to ours bones. Calcium is a mineral that is
particularly hard to digest, and if we don’t drink
enough water, well you get the picture.
The list of water must haves is of course much longer.
Let's start with the vital organs. This includes the heart,
lungs, kidneys, pancreas, liver, stomach, male and female
reproductive organs, eyeballs, tongue, and let's not forget
the appendix. The ligaments follow – all of them,
and then muscle tissue, the nails, ears, skin (all), and
of course the lips. In all probability some important body
part got left off the list, but you get the general idea.
When the body is over exerted (excessive manual labor or
exercise), more water is needed to avoid dehydration. During
these conditions it would be plausible to suggest that even
more then the recommended eight glasses is needed for replenishing
and rebuilding.
Let's not forget those “other” beverages –
the ones that need digesting. Although most of these have
water as the main ingredient, as mentioned digestion impacts
water absorption and can even create retention, which means
that drinking other beverages could mean we are consuming
LESS WATER. When the beverage contains alcohol, the amount
of water absorbed is even less significant.
Taking all this into consideration, the next time a nice
waiter or waitress stops by your table to deliver or refill
that all-important AND FREE glass of water, give that person
a warm smile and remind yourself that today the number of
glasses of water left to drink has been reduced by one glass
- or perhaps even two!
Water:
How much should you drink every day?
